l-lIRAM Li. VAUGHAN, OF SAN FRANCISCO, CALIFORNIA WINDOW-CLEANING DEVICE.

To all whom it nul'y concern:

Be it known that l, IIIRAM G. Vacensx, a citizen of the Lnited States of America, and a resident of the c1tv and county of San e lfltlIlClSCO, in the State of (.tlllfOlllltl, have nvented a new and useful Window-Cleanmg Device, of wlnch the following is a I specification, reference being had therein to the accompanying drawing. This invention has relation to window cleaning devices, and it consists in the novel construction and arrangement of the parts as hereinafter shown and described.

The object of the invention is to provide adevice of the character indicated, which is especially ada ted to be used upon car windows and which may be easily and readily operated for the purpose of keeping such windows free from accumulated moisture, frost, etc., in order that the operator having charge of the car may have an unobstructed view of the track ahead.

The special object of the invention is to provide a. .device which will clean the winow without any tendency to binding or hitching, and with this object in view the cleaner oonsists primarily of a bar having a rubber and which is arranged to move in guides located at the sides of the window. single spring roller islocated above 'the window and tapes are arran ed to wind upon the said roller and are a so connected with the bar. A draw cord is attached at its ends to said barand passes under pulleys and through apertures provided in the front of the car, whereby its intermediate portion is within convenient reaching distance of the operator.' By reason of the fact that all of the said tapes are mounted upon the same spring-actuated roller and not upon a plurality of such rollers as is sometimes the case, there is no chance for the said tapes to wind or unwind from the said roller in an uneven manner. Consequently, all. tendency for the said bar to bind in its guides is eliminated. In moving vehicles of the character stated, it is essential that such cleaners move promptly and positively when operated, for ot erwise if any of the parts of the cleaner should become caught or disarranged in cases of emergency, accidents of more or less seriousness may be the result.

In the accompanyin drawings,Figure l is a front elevation of a .car provided with the window-cleaning device. .Fig'. 2 is a Specification of Letters Patent.

vertical sectional view of a front end of a 1 car provided with the device. Fig. 3 is a 1 horizontal sectional view of the front end of a car provided with the device Fig. at is a transverse sectional view of the device. Fig. .3 is a side elevation of the spring roller with parts thereof in section. Fig. 6 is a view looking at one end of the roller, and Fig. 7 is a view looking at the opposite end of the roller.

The bar 1 is provided upon its inner side with the strip 2. Said strip may be of rubber or other flexible material. The guides '3, 3, are vertically arranged upon the sides l of the window, and receive the ends of the bar 1. The parts of the device are arranged at the end 5 of the car. The roller 6 is journaled for rotation in the brackets T, T, which are located at the top of the front 5 of the car. The tapes 8 are arranged to wind upon the roller 6 and are attached at their lower ends-to the bar 1. The drawcord 9 is attached at its ends to the bar 1, and passes under the ulley l1 and through the apertures 10 provlded in the front 5 of the car. The hood 12 is attached to the upper portion of I1 9 front of the car 5 and ice over the rol er 6 and forms a housing for the same. The roller 6 is provided in its interior with a coiled sn'ing 13, which surrounds the shaft ll. us end of the said spring is made fast to the roller and the other end thereof is fixed to the shaft 14. The said shaft is journaled at its outer end portion in a cap 15, which forms a closure for the compartment in the roller 6 which contains the spring 13. The opposite end of said roller 6 is provided with a cap 16, and the intermediate portion 17 of the draw cord 9 affords means whereby the operator mav grasp the said cord for the purpose of drawing the bar 1 and the strip 2 down along the outer surface of the window. The pintle of the cap 16 is circular and is journaled in one of the brackets cular and is retained in a similar opening provided in the other bracket 7.

From the foregoing description it is obvious that as the draw cord 9 is pulled within the car the bar 1 and the strip 2 .will, descend along the window and that'the tension of the 5 ring 13 will be increased by reason of the act that the ta es 8 are unwound from thejroller 6. onsequently, when the draw cord' 9 is released the spring 7, while the end of the shaft 14 is non-cirl?- wilt rotate the roller (3 in the opposite dination and rewind the tapes 8 evenly upon the periphery of the roller 6. ma eral tapes :5 are used and there is but one priinpaetnated roller upon which they all \Yllltl and from which they all unwind, there ie no rhanee for one tape to unwind or wind upon the said roller more rapidly than all at the other tapes. Tl'lerelore, the bar l will always more in a true horizontal position and cannot can't or bind in. the guides 3.

Having 'dwrrihed my invention, what 1 tltllll] a: new and (lesire to secure by Let tersfluent. isz-- A window cleaning deviee COIIIPilSlD a bar. a llexihle strip mounted upon the liar and ha ring eontact with the Surface of the window. guides vertically located at the sides of the window and receiving the ends Tnasin uoh as of mid iar, a Angle springeetnatecl roller journaled for rotation above the window, a proteeting' hoi'ising therefor, a plurality of tapes attached to said roller, the lower ends of said tape being conneeted to the bar, pulleys journaled below the window, the window frame having apertures located below said pulleys. and a draw cord attached at its ends to the har and paesing under said pul 103 and through said apertures and having its intermediate portion located along the inner lower side of the window.

In testimony whereof I allix my sigi'iature in presence of two witnesses.
